Po zebraniu chcę rozpakować karton z dokumentami i posprzątać biurko.

Because the preposition po meaning after requires the locative case in Polish.

• nominative: zebranie = meeting
• locative: zebraniu = after/in the meeting context

So:

• po zebraniu = after the meeting

This is a fixed and very common pattern:

• po obiedzie = after lunch
• po pracy = after work
• po lekcji = after class

Zebranie usually means a meeting, often a more formal or organized one, such as a staff meeting, office meeting, school meeting, or committee meeting.

Spotkanie is also meeting, but it is broader and can be formal or informal. It can also mean a social get-together.

So in an office sentence like this, zebranie sounds very natural if you mean an organized meeting.

Because Polish often omits subject pronouns when they are already clear from the verb form.

• chcę already means I want
• the ending -ę tells you the subject is I

So:

• chcę rozpakować... = I want to unpack...

You could say Ja chcę..., but that usually adds emphasis, like I want to... rather than someone else.

After chcę = I want, Polish normally uses the infinitive, just like English often does.

• chcę rozpakować = I want to unpack
• chcę posprzątać = I want to tidy up / clean up

In this sentence, both infinitives depend on chcę:

• chcę rozpakować karton... i posprzątać biurko
• literally: I want to unpack the box... and tidy the desk

So one chcę controls both actions.

They are perfective because the speaker is talking about completing those actions.

• rozpakować = to unpack completely
• posprzątać = to tidy up / clean up completely

This fits the idea of a planned, finished result:

• unpack the box
• tidy the desk

If you used imperfective verbs, the focus would be more on the process or repeated activity:

• rozpakowywać = to be unpacking / to unpack repeatedly
• sprzątać = to clean / be cleaning / clean regularly

After chcę, both aspects are possible, but they mean different things:

• Chcę rozpakować karton. = I want to unpack the box completely.
• Chcę rozpakowywać karton. = I want to be unpacking the box / I want to do the activity of unpacking it.

In this sentence, perfective is the natural choice.

Karton usually means a cardboard box or carton.

In this sentence, it most likely means a box, probably one containing documents.

So:

• rozpakować karton = unpack a box / unpack the contents of a cardboard box

Depending on context, English might translate it as box rather than carton, even though the Polish word is karton.

Karton z dokumentami literally means a box with documents.

This construction focuses on the box and says what is in it or associated with it:

• karton z dokumentami = a box containing documents

Polish also allows expressions like karton dokumentów, which can sound more like a carton/box of documents. That version can feel a bit more like describing quantity or type.

In this sentence, karton z dokumentami is a very natural way to say the box with documents.

Dokumentami is instrumental plural.

That is because the preposition z has different meanings and uses different cases:

• z + instrumental = with
• z + genitive = from/out of

Here it means with, so we use instrumental:

• karton z dokumentami = box with documents

Forms:

• singular: dokument
• plural nominative: dokumenty
• plural instrumental: dokumentami

Compare:

• z dokumentami = with documents
• z dokumentów = from the documents / out of the documents

Biurko is the direct object of posprzątać, so it is in the accusative case.

However, biurko is a neuter noun, and for many neuter nouns the accusative singular looks the same as the nominative singular.

So:

• nominative: biurko
• accusative: biurko

That is why the form does not visibly change.

Compare with a masculine animate noun, where the accusative often does change:

• nominative: student
• accusative: studenta

But with biurko, nominative and accusative are identical.

It can mean either, depending on context, but tidy up the desk is often the best fit.

The verb posprzątać is broad. It can mean:

• tidy up
• clean up
• put in order

So posprzątać biurko could mean:

• remove clutter from the desk
• organize papers
• wipe it down
• generally leave it neat

If the context is office work after a meeting, tidy up the desk is a very natural interpretation.

Yes. Polish word order is relatively flexible, although some orders sound more neutral than others.

The original sentence:

• Po zebraniu chcę rozpakować karton z dokumentami i posprzątać biurko.

This is a natural, neutral order: time expression first, then the main idea.

Other possible orders include:

• Chcę po zebraniu rozpakować karton z dokumentami i posprzątać biurko.
• Karton z dokumentami chcę po zebraniu rozpakować i posprzątać biurko.

These are grammatically possible, but they may shift emphasis. The original version sounds the most straightforward and natural in ordinary speech.

Not necessarily. It usually means after the meeting, but it does not by itself say immediately after.

It could mean:

• right after the meeting
• later, once the meeting is over

If you wanted to stress immediately after, Polish might use extra wording such as:

• zaraz po zebraniu = right after the meeting
• od razu po zebraniu = immediately after the meeting

So po zebraniu is neutral and simply places the actions after the meeting.

The grammar points most directly to unpacking the box:

• rozpakować karton z dokumentami = unpack the box with documents

In real usage, though, the intended meaning is often that the speaker will open the box and take out / arrange what is inside. So practically, the documents are part of what gets unpacked.

If you wanted to focus more directly on the documents, you could say something like:

• rozpakować dokumenty z kartonu = unpack the documents from the box

But the original sentence is perfectly natural.

Here i = and connects two infinitive phrases:

• rozpakować karton z dokumentami
• posprzątać biurko

Both are things the speaker wants to do after the meeting.

So the structure is basically:

• Po zebraniu
• chcę
• [rozpakować karton z dokumentami] i [posprzątać biurko]

That is very common in Polish: one verb like chcę can govern multiple infinitives joined by i.
